81 Piece Economy Rectangular Gage Block Set

Fowler "Economy/Workshop" grade Gage Block Sets are identical to our standard sets in all respects, except for the wider range of tolerance which is more than adequate for a majority of shop needs.  Blocks are rectangular, constructed of the finest grade of high carbon/chrome steel, fully stress relieved, hardened to 65 RC, lapped and mirror polished to a very low micro-surface finish.  Blocks feature a low coefficient of thermal expansion, and they are carefully inspected for accurate size, parallelism and flatness.

Features:

• ±.000050" accuracy for a lower price, each department can now have their own set.

• Standard industrial sizes ensure complete interchangeability with all accessories.

• Each set complete with deluxe fitted case and Certificate of Inspection traceable to the National Institute of Standards & Technology.
